This invention relates to improvements in tilter devices for use intilting metal billets and sections `to be rolled, being particularlyapplicable to devices for use in tilting and holding up 5 square orapproximately square or diamondshaped billets when rolling in diamondpasses. A tilter device comprising a cooperative pair of work-engagingheadsconstructed in accordance with the present invention is illustratedin the accompanying drawings in which Fig. 1 is an end elevation, Fig.y2 a plan view, Fig. 3 a longitudinal vertical section on the line w-a ofFig. 1, and Figs. 4-6 fragmentary views of vthe tilter heads. I y

The tilter device shown comprises a pair of tilter heads I, Iaconstituted as iiuted conoidal members adapted for engagement in opposedrelation with a metal billet 2 undergoing treatment ina rolling mill.

Each tilter head I or Ift is xed to or unitary with a toothed sector 3mounted for partial rotation about its axis 4 in a link structureincluding a pair of links 5 mounted for pivotal movement about the axisI of a pinion 'I meshing with the sector 3 and with a pinion 8 on ashaft 9 carrying also a gear wheel I0 meshing with a pinion I I on therotor shaft of a reversible electric driving motor I2. The axis 4 of thesector 3, the axis 6 of the pinion 1, the axis of the shaft 9 and theaxis of the pinion II are all parallel to the line of travel of thebillet through the mill.

The arrangement is such that each sector 3, as well as being rotatableabout its own axis 4 by actuation of the respective electric motor I2,is free to move bodily in an arc about the axis 6 spaced from the axis 4in accommodating itself to the movement of the billet 2.

Each tilter head I or Ia may be moved to an inoperative upper positionas at A or an inoperative lower position as at B (Fig. 1).

Each tilter head assembly is incorporated in a frame structure I3` orI3a mounted upon the feed table of the rolling mill and movable trans-`versely of the line of travel of the billet 2. I4

45 denotes the roll housing of the rolling mill.

In operation, the tilter heads I and Ia are suitably angularly adjustedto tilt the billet in the required direction, one head being used as anl abutment and the other head being actuated to y tilt the billet, asshown in Figs. 4 and 5, in which 5 tion of the billet. Figs. 4 and 5show the heads operating on a billet of comparatively large size, whileFig. 6 shows the heads operating on a billet of comparatively smallsize. As is understood, the sector 3 of the manipulating head la isiioatingly supported by the respective pair of 5 links 5 which thuspermit the sector to adjust itself vertically as required in theco-operation of the head Ia with the billet 2.

I claim:-

1. In a metal rolling mill, a tilter device cornprising at least onemovable tilter head, a toothed sector carrying said tilter head havingits axis parallel with the direction of travel of the work, and a pinionmeshing with said sector and having its axis parallel with and spacedfrom the axis of said sector, said sector being rotatable about its ownaxis, and movable bodily in an arc about the axis of said pinion.

2. In a metal rolling mill, a tilter device movable transversely of thedirection of travel of the work, said device comprising a work-engaginghead, a toothed sector carrying said head and rotatable about an axisparallel with the direction of travel of the work, a pinion meshing withsaid sector and having its axis parallel with and spaced from the axisof said sector, and a link structure mounted for pivotal movement aboutthe axis of said pinion and carrying said sector.

3. In a metal rolling mill, a frame movable `transversely of thedirection of travel of the work, 0 and a tilter device incorporated insaid frame, said tilter device comprising a work-engaging head, atoothed sector carrying said head, and having its axis parallel with thedirection `of travel of the work, a pinion meshing with said sector andjournalled in said frame for rotation about an axis parallel with andspaced from the axis of said sector, and a structure mounted for pivotalmovement about the axis of said pinion and carrying said sector.

4. In a metal rolling mill, a frame movable transversely of thedirection of travel of the work, and a tilter device incorporated insaid frame, said tilter device comprising a work-engaging head, atoothed sector carrying said head, and having its axis parallel with thedirection of travel of the work, a pinion meshing with said sector andjournalled in said frame for rotation about an axis parallel with andspaced from the axis of said sector, a structure mounted for pivotalmovement about the axis of said pinion and carrying said `sector, areversible motor mounted on said frame for rotation about an axisparallel to the axis of said sector, and a gear train connecting saidmotor with said pinion.

5. In a metal rolling mill, a tilter device movable transversely of thedirection of travel of the work, said tilter device comprising aWork-engaging head, a toothed sector carrying said head,

5 and having its axis parallel with the direction of travel of the work,a pinion meshing with said sector and having its axis parallel with andspaced from the axis of said sector, links mounted for pivotal movementabout the axis of said pinion and carrying said sector, a reversiblemotor rotatable about an axis parallel with the axis of said sector, anda gear train connecting said motor with said pinion.
